Throttle back to LB and LTrigger
Sorry, I'm one of those controller-players. PLEASE PLEASE put throttle back onto the left button and left trigger (reverse and forward thrust respectively) Everything about the new demo feels and looks awesome except that the controls have been changed. At least tell me you'll add configurable controls in a future update so I can change it. It's just WAY more comfortable to squeeze the trigger to travel than to shove the stick exactly straight for your whole trip, even with the new drive speeds.
